Chapter 11, Problem 37P

A researcher sequences the whole exome of a patient suffering from Usher syndrome, a rare autosomal recessive condition that is nonetheless the leading cause for simultaneous deafness and blindness. The exome sequence does not show homozygosity for any polymorphisms different from the human RefSeq.

a. How could the researcher examine the data already gathered to try to find the disease gene, assuming the sequence is accurate?
b. If the attempt described in part (a) was unsuccessful, the researcher might contemplate sequencing the patient’s whole genome. What are the potential pitfalls of this strategy?

It has been suggested that it would make the study of human diseases easier if cloned transgenic animals were produced that carried faulty versions of human genes (e.g., the gene that causes cystic fibrosis). a. Why would such animals be useful in medical research? : b. What ethical questions are raised by the creation of such transgenic animals?
Suppose that you could undergo genetic testing at age 18 for susceptibility to a genetic disease that would not appear until middle age and has no available treatment. a. What would be some of the possible reasons for having such a genetic test and some of the possible reasons for not having the test? b. Would you personally want to be tested? Explain your reasoning.
